After more investigation I found out that KDE was playing spoil sport.
When I loged in with Gnome, sound worked. After that when I tried
logging in with KDE, sound didn't work. Thus KDE login was causing some
problem. I removed all the KDE settings from my account and tried
logging in. Walla! Everything worked as expected. KDE login audio
greeting was back as earlier and other sounds are working fine.

The KDE problem has happened the second time. I have had to remove the
KDE settings to get sound working. I am still confused as to what causes
this corruption or when it happens.

So, for making the sound to work I had to do the following:

1. ~$ /etc/init.d/alsa stop
2. ~$ rm /var/lib/alsa/asound
3. ~$ /etc/init.d/alsa start

4. Log out of KDE and remove all KDE settings

Thanks to everyone who helped.
